Describe in detail

Referring to the drawings and referring initially to Fig. 1 in accompanying drawing to 20, illustrating can respond the uropoiesis pressure of applying The uropoiesis valve 1 for automatically opening up.

Valve 1 includes polymer valve body, and the polymer valve body has outer support region, and the supporting zone has edge 2；At least Three flaps 3,4,5；With body region 6, support edge along 2 and flap 3, between 4,5 extend.Flap 3,4,5 extends internally simultaneously End at end face 7,8,9 respectively.Each flap 3,4,5 has pillar a, b, and pillar a, b are relative to each other according to 120 ° of angle Extend.When valve is in normal switching-off structure, adjacent pillar is to 3a；4a；4b；5b；5a；3b engages to close between flap Space.

The first structure of valve is normal switching-off structure, and in normal switching-off structure, flap 3,4,5 is engaged with shutoff valve.The Two structures are the Unclosing structures for allowing flow of fluid, and in Unclosing structure, flap 3,4,5 is opened, so that flap pillar is to 3a； 4a；4b；5b；5a；3b responses power F1 is opened and separates, to allow to flow through the valve.Valve can also respond external force F2 and be opened, For example, if through the medicine equipment of such as conduit, external force F2 may be applied.

The various structures of valve 1 are illustrated in Figure 11 to 20.In first or normal switching-off structure (Fig. 9,15), valve Lobe 3,4,5 is engaged.

When uropoiesis pressure F1 is put on into valve body, the power initially pushes flap 3,4,5 so that they are pressed against each other, and If pressure is more than setting value, valve body will varus.The beginning of varus is explained in figure 16.When response valve power F1 is beaten completely When opening, valve body (and flap 3,4,5) is extended downwardly, as shown in Figure 10 and 17.This allows liquid stream to pass through the valve.When liquid stream stops When only, valve body will return to original knot by returning to the turning up for bias of normal switching-off structure in response to polymeric material Structure, and flap extends as shown in figures 11 and 15.

When power F2 is put on into flap 3,4,5, flap pillar is to 3a；4a；4b；5b；5a；3b opens to allow such as to cure The target of apparatus is treated through (Figure 13,20).Figure 19 represents that response power F2 partially opens structure.When apparatus is withdrawn, power is removed F2 and flap 3,4,5 returns to closed position (Figure 13) under the intrinsic bias of the polymeric material of valve body.

Flap 3,4,5 is reinforced in the region of engagement.In this case, by polymeric material in this region Partial thickening realizing this point.Similarly, support edge is reinforced along 2 by the partial thickening of polymeric material.

The region of the engagement of flap 3,4,5 has axial length, and the axial length is typically 1 to 5mm.This guarantees to work as valve In normal switching-off structure when, the just engagement of the flap on very big interface zone.In the thickness of the flap in the region of engagement Typically between 0.1mm and 10mm.

By the property (such as, density) for changing the material of valve, the yield pressure that valve can be adjusted to adapt to change.Valve leads to Cross when under the pressure controllably varus realizing this point.

The valve 1 of the present invention returns to its original operating position after fully opening.In the situation for not damaging operating valve Under realize this point.

When valve is opened by the uropoiesis pressure and the fluid stream that apply, flap is opened.The outer surface of valve has bigger Anti- deformation behavior, therefore, in the direction open main body needed for Li Genggao.

The key property for affecting the function of valve is flap pillar impinging one another.By the geometric form for changing flap 3,4,5 Shape and length, can be such that valve 1 opens in one direction at various pressures.Open in opposite direction and slightly less than depend on The geometry of flap, but be more dependent on manufacturing the elasticity and density of the material of the device.In addition, overall diameter and flap are beaten The diameter opened affects the tensile force along both direction.

Valve can have any suitable biocompatible polymeric material.It can have the property for allowing valve to operate as described above Biocompatible polymeric material.

Material for producing the valve has the % elongations of 50%-3000%.The material is anti-also with 0.01-5Mpa Tensile strength.In addition, the material can have antibacterial action, to prevent from colonizing when in vivo.In addition, the material can be It is elasticity or viscoelastic, and can be alternatively open celled foam.The density of the material should be in 0.1g/cm3 to 1.5g/ Between cm3.

Valve can have the flap of any desired quantity, and for example, the valve 30 illustrated in Figure 21 to 26 has six flaps 251.These flaps 251 are oriented orthogonal to the direction of liquid stream, to additionally allow for the bigger dilatancy of clear valve diameter.

Similar to valve described above, and comprising polymer valve body, the polymer valve body has the outer support of nearside to valve 30 Region, the supporting zone has edge 32；Six flaps 33；With body region 36, it is in support edge between 32 and flap 33 Extend.Flap 33 extends and ends at distal face 33.Each flap has pillar, and pillar is relative to each other according to 60 ° of angle Extend.When valve is in normal switching-off structure, the space of adjacent pillar to engaging to close between flap 33.

The first structure of valve 30 is normal switching-off structure, and in normal switching-off structure, flap 33 is engaged with shutoff valve.Second Structure is the Unclosing structure for allowing flow of fluid, and in Unclosing structure, flap 33 is opened, so that flap pillar is to responding power F1 It is opened and separates, allows to flow through valve 30.Valve can also respond external force F2 and be opened, for example, if the doctor of such as conduit When treatment apparatus is passed through in valve, apply external force F2.

The various structures of valve 30 are illustrated in Figure 21 to 26.In first or normal switching-off structure (Figure 21), flap 33 Engagement.

When uropoiesis pressure F1 puts on valve body, the power initially pushes flap 33, so that they are pressed against each other (Figure 22), and And if pressure be more than setting value, then valve body will varus, as shown in Figure 23.When response valve power F1 is fully opened, valve master Body (and flap 33) is extended downwardly, as shown in Figure 23.This allows liquid stream to pass through the valve.When liquid stream stops, valve body will Prototype structure is returned to by the bias of normal switching-off structure being returned in response to polymeric material turning up, and in flap such as Figure 21 Shown extension.

Figure 26 represents that response power F2 partially opens structure.When apparatus is retracted, power F2 is removed and flap 33 exists Closed position is returned under the intrinsic bias of the polymeric material of valve body.

Flap 33 is reinforced in the region of engagement.In this case, by polymeric material in this region Partial thickening is realizing this point.Similarly, support edge is reinforced along 32 by the partial thickening of polymeric material.

The engaging zones of flap 33 have axial length, and the axial length is typically 1-5mm.This is guaranteed when valve is in just Often during closing structure, the just engagement of the flap on very big interface zone.Engagement region flap thickness typically For 0.1mm-10mm.

Valve 30 needs different power to open along different directions.By the property (such as, density) for changing the material of valve, can With the yield pressure for adjusting valve to adapt to change.Valve 30 by being placed in pressure under when controllably varus realizing this point.This Bright valve 30 returns to its original operating position after fully opening.This is realized in the case where operating valve is not damaged Point.

A key property for affecting the operation of valve 30 is flap pillar impinging one another.By the geometry for changing flap 33 Shape and length, can be such that valve 30 opens in one direction in different pressure.Open in opposite direction and slightly less than rely on In the geometry of flap, but it is more dependent on manufacturing the elasticity and density of the material of the device.In addition, overall diameter and flap The diameter of opening affects the tensile force along both direction.

Valve can be any suitable biocompatible polymeric material.It can have permission valve to operate as described above The biocompatible polymeric material of property.

Material for producing this valve has the % elongations of 50%-3000%.The material is anti-also with 0.01-5Mpa Tensile strength.In addition, the material can have antibacterial action, to prevent from colonizing when in vivo.In addition, the material can be It is elasticity or viscoelastic, and can be alternatively open celled foam.The density of the material should be in 0.1g/cm3 to 1.5g/ Between cm3.

With reference to Figure 41 to 43, single collar part 650 can be used to control the installation of valve 600, collar part 650 has prominent Go out part 651, ledge 651 extend in the edge of valve body with control valve 600 from Unclosing structure move to closing structure and/ Or move to the pressure of Unclosing structure from closing structure.By length X for adjusting ledge 651, the pressure can be changed. For example, short length can allow valve to move freely, and long length will control the movement between closing structure and Unclosing structure.With Methods described, by suitably adjusting the length of ledge 651, single valve can be used for many different applications.

Figure 44 to 48 represents the embodiment for using of the uropoiesis valve for being connected to the such as catheter of Foley conduits 620.

Figure 49 to 52 is the diagram similar to Figure 44 to 48 for representing replacement device, and in the apparatus, valve gear is included In the near-end housing of catheter.

The uropoiesis valve gear of the present invention is made up in specific embodiments of polymerization viscoelastic material.The use of this material Solve many problems related to conventional equipment.In first technique, urinary device is by metal and relatively hard material system Into.When these first process units are placed in be contacted with soft tissue, these first process units can result in reconstructed tissue, thus Tissue can be corroded or fibrillatable and be hardened.In addition, contacted with soft tissue using hard material can result in stimulation and Subsequently result in the discomfort of patient.

The urinary device of the present invention has the feature realized using polymerization viscoelastic material.Viscoelastic polymer material is formed Valve, valve is normally closed, but can turn up when pressure is exposed to.The ability phase that the mechanism that valve turns up deforms under stress with material Close.Viscoelastic material deformation under stress can also be affected by applying the stressed duration.

The material for using can be with as described below.The material can also be as described in our US2011-0152395A, and this is special The full content of profit is herein incorporated by reference.

Various uropoiesis valves described here can be made up of suitably polymerization viscoelastic material, the reality of such as following material part Apply described in example 5.

The opening pressure and flow of the valve of the type shown in Figure 28/29 more than test by the material manufacture.Obtain Result below.

Result explanation in upper table, has in required specification with many valves that the density of 0.95-1.07g/ml is manufactured Opening pressure, but do not leak when the valves are closed.Through valve flow also it is noted that because this can be in the rational time In the range of realize that bladder is emptied.

The invention further relates to provide the improvement of the device (such as, conduit) of pipeline, bacterium can enter interior by the pipeline Portion's anatomical structure.Especially, the present invention relates to urinary drainage tube.However, techniques described below can also relate to it is long-term and short Conduit on phase eduction gear, such as pubic arch, percutaneous endoscopic gastrostomy (PEG) pipe and bacterium can be provided being capable of Jing its entrance Other devices of the pipeline of internal anatomy.

In the case of inlying catheter and device, it is known that the bacterium of extracorporeal is promptly propagated along urethra, causes uropoiesis Infect and biofilm formation in road.

The propagation of the proteus mirabilis (Proteus Miribellis) in urinary device causes salt and mineral from urine Precipitation, causes the final crust of device tube chamber, causes blocking.Although carrying out preventing many of this impact using antimicrobial coating Attempt, but do not find long-term solution, and catheter will become blocking in 3-4 time-of-week sections.

Foley catheters kept constant past 60 years.Well accepted to be, 100% indwelling Foley conduits will be 4 Become to crust and block in the range of time-of-week.Substantial amounts of commercial efforts concentrate on the life-span for increasing these devices, because long-term use Family needs special care to be frequently changed these devices, and this is costly.

There is the teaching of a myriad of for the various antimicrobial coatings of drainage tube and the first technique that uses of insert It is open.US4603152 is described for the antimicrobial coating of intubation catheter etc..US7601361 describes durable antimicrobial coating. US4932948 describes the antibacterial insert for Male urethral catheter.US5782808 describes antibacterial pipe material connector.

One problem of prior art is, most antiseptics only minimally contribute to preventing the propagation of bacterium and Subsequently by the crust of eduction gear caused by these bacteriums.In addition, the antiseptic in many uses can result in bacterium to using In antiseptic produce resistance.

Many work are had been carried out to coat inlying catheter using antimicrobial coating, to make great efforts to prevent biofilm formation.This A little coatings or invalid, or the enough durabilities for not maintaining antibacterial effect.

With reference to Figure 53 to 55, illustrate for from traditional urinary drainage tube 500 of the draining urine of bladder 501.Conduit is included Pipe 502, pipe 502 has entrance 503 and outlet 504, and urine is drained by entrance 503 and outlet 504.Conduit 500 has to be used In the bulbous 505 for making conduit be held in place in bladder.The conduit of traditional type is commonly known as Foley and leads Pipe.In use, urine is dropped onto in collecting bag from conduit outlet 504.The conduit has the shortcomings that very big, can occur entering Mouthfuls 503 nearby and bacterial colonizations and crust in conduit cavity, respectively as shown in Figure 54 and 55.

In the present invention, drainage tube 550 has the valve 551 for control through the flow of conduit.Figure 56 and 57 is represented and worked as Valve 551 is in the conduit 550 during closing structure.Valve 551 allows bladder to be filled on the level of duct entry 503.In valve 551 While closing, the accumulation of the urine in conduit cavity may start the process that bacterial biof iotalm is formed and crusted, in such as Figure 57 It is shown.

With reference to Figure 58 to 60, when valve 551 is spontaneously opened, the pressurization urine stream through conduit is produced, until bladder 501 In the height of urine drop below the level of duct entry 503.Being applied periodically of this pressurized stream produce enough power with Prevent bacterial biof iotalm from accumulating in duct entry and accumulating in conduit cavity, respectively as shown in Figure 59 and Figure 60.

In the present invention, check valve is comprised in conduit, is especially included in catheter.The valve is designed to not Leakage, but its closed position is opened and returned to after bladder is emptied under predetermined yield pressure.It is described predetermined Yield pressure may correspond to by patient by abdomen power that is conscious nervous or being produced due to normal movement.It is known single The power stood or sit produces very big abdominal pressure.In this case, valve is designed to be placed between conduit and urine collecting bag In pipeline.Valve facilitates the circulation of bladder to be full of and empty, therefore facilitates periodically washing away for conduit cavity.Emptying for bladder can be due to Movement is caused, and can be conscious or unconscious.

Present invention teach that it is a kind of be conveniently employed in the diverse scheme of scheme for realizing antibacterial effect.In the present invention In, physics and mechanical device are used to realize antibacterial effect, therefore avoid the need for the coating to possibly cytotoxicity.In addition, This scheme represents durable and lasting effect, and the of short duration effect that non-used antimicrobial compound is seen.

Accelerate microorganism testing (Figure 61) it was demonstrated that compared with open Foley conduits, bio-compatible described herein Property foamed material tricuspid clack valve be included in Foley conduits, " time of crust " almost 4 times will be extended.Can hand with being provided with The conduit of the ball valve that building site is moved between Unclosing structure and closing structure is compared, and the valve of the present invention also shows significantly more preferable. A kind of first technique valve of search can be obtained according to trade name FlipFlow.

The present invention provides a kind of valve for controlling the urinary incontinence.Valve is opened under specific bladder pressure, in one case, When bladder is full of (or in required volume), valve is opened in the case of without any manual manipulation.Bladder will be with In being emptied into the drainage bag for connecting afterwards, and valve will return to closed position.This has easy-to-use benefit.Carried using valve For interval, discrete excretion has been shown as that catheter blockage can be reduced.Most possibly being subjected to those users of catheter blockage is The user of symptom is coexisted with other, many symptom coexisted in symptom cause flexibility or mobility.

The valve helps to use conventional pilot pipe valve but discontinuous still through interval excretion will drain in very great Cheng The patient for maintaining " normal " bladder function is benefited from degree.

In vitro, the research of laboratory model of the bladder for being inserted with conduit is performed to investigate and " Flip-flo " (Bard The trade mark of Inc) time of the blocking of valve of the invention for comparing with continuous excretion model of valve.Bladder model is by Striker etc. People in Stickler, D.J., Morris, N.S. and Winters, C. (1999). " the biomembranous formation on research urethral catheter With the simple physical model of physiological function（Simple physical model to study formation and physiology of biofilms on urethral catheters.）”Methods in Enzymology,310:494 Described in.

Compared with continuous excretion model, the valve of the present invention shows the length of the duration of congestion for dramatically increasing (110.4vs.22.9 hours, p value 0.001)." the Flip- aided in normal excretion " Flip-flo " valve and by automatic injection pump There is no significant difference (40.0vs.45.1 hours, p value 0.425) between flo " valves.With the 45.1 of automatic Flip-flo little phases Than for the valve of the present invention, average duration of congestion is 110.4 hours.This result highly significant (p value 0.004).

Bladder model is by the glass chamber being maintained at by water jacket at 37 DEG C（Bladder）Constitute.With autoclaving to each mould Type sterilizes, and size is then passed through one section of silicone tube in model base for the Romed conduits based on latex of 14ch（Urethra） In being inserted into bladder cavity.By with 10ml deionized water expanding baloons, guaranteeing that conduit is gone up in position in the outlet of bladder. If appropriate, then the end of conduit is connected with the valve of the present invention, or is connected with Flip-flo valves, or keeps Open continuously to drain.Flip-flo valves and continuous excretion model are subsequently connected in a usual manner with zone of discharge, simply the present invention Valve and automatic Flip-flo valves keep drain in the plastic beaker of covering（To allow due to the pressure that applies from syringe pump Opening system）.Aseptic urine is pumped in chamber, so that before discharge conduit collecting bag/beaker is flow through, resid vol is received Collection is under conduit eyelet.

With with without automatic injection pump, Flip-flo valves are connected with routine Foley conduits, and every within the cycle of 12 hours Four hours are intermittently opened, and continuous excretion are then all switched to overnight, until blocking.In routine use, Flip-flo valves are used in interval excretion during daytime, and can continuously drain at night.The system is used in testing, with to the greatest extent Conventional use may fully be repeated.

The a large amount of benefits of patient are supplied to according to the conduit equipped with valve of the present invention：First, need not continuously wear not all day Refined zone of discharge, secondly, it additionally aids and retains some bladder muscle tension force, because bladder is periodically full of and empties, such as The situation of " normal " bladder.In addition, urine is full of the biomembranes that instead of some exploitations, the biology through the periodicity of conduit Film ultimately results in catheter blockage, thus increased the life-span of conduit.Vysera valves provide extra benefit, such as increase potentially large number of User, including those of sensitive and mobile difficulty, and by allowing to be drained in the batch (-type) for occurring whole night and during daytime, Increase the life-span of conduit.

Figure 62-65 illustrates the uropoiesis valve in the indwelling valve gear 600 to be retained, using its in balloon 630 or bladder His anchor.Valve 600 may be mounted on tubular supporting piece 635.Can have and hang tether 631 for covering valve outside 600。

Figure 66 and 67 illustrates the uropoiesis valve 600 from reservation structure 635 being located in urethra.It can with adhesive or It is secured in place by grappling or suturing skill.

The self-control mechanism of body is in urethra.Urethral closure mechanism is by external sphincter and neck of urinary bladder（Or internal sphincter）Structure Into.When deflated, it causes the urethra of about 40mm length to be closed.

In the urethra closed or block, any abdominal pressure risen due to strain acts on lateral vesical and neck of urinary bladder On.In routinely self-control patient, due to the pressure it is equal, but effect is conversely, during storage stage（When bladder is full of）, Generation is not revealed.

Excretion or urination stage start from closing the lax of the internal force of urethra, and especially external sphincter is lax and neck of urinary bladder is opened Put.It is detrusor contractions after this, Fluid pressure is produced in bladder, causes urine to flow.Importantly, the fluid in bladder Pressure does not affect opening [Paul the Abrams, " urodynamics of neck of urinary bladder or external sphincter（Urodynamics）", the third edition, Springer, page 13].

During urinating, when urethra and neck of urinary bladder are fully opened, the applying of abdominal pressure only affects the bladder wall, and does not affect urine Road or neck of urinary bladder.During the urination being not blocked from, the only effect for applying abdominal pressure is to increase intravesical Fluid pressure, so as to increase Plus flow velocity, this is [Paul the Abrams, " urodynamics for extensively being recognized（Urodynamics）", the third edition, Springer, 84-85 page].

If urethra is by partial blockage, the applying of abdominal pressure is by the sealing for affecting neck of urinary bladder and the supercharging of lateral vesical. In this case, net effect is the intravesical Fluid pressure of antagonism, so as to prevent flowing.

Many technologies are had been developed for for processing urethra internal fault, it generally focuses on the endo-urethral sealing of improvement.Its Example be by collagen injection with neck of urinary bladder in, to strengthen internal sphincter mechanism.

US6063119 and US5989288 are described by placing prosthese in upper urethra and bladder neck area, make internal sphincter The closing expansion of mechanism.The effect of the device be when the outside of force compresses neck of urinary bladder and urethra is routinely dissected, sealing urethra with Prevent from revealing.

Conversely, in the present invention, uropoiesis valve is located in bladder, not by the pressure influence in urethra.In fact, valve need not It is any to dissect power to keep sealing, the pressure of the urine in its antagonism bladder.When belly hydrostatic pressure is on the outside of bladder, Valve provides the back-pressure suitable with the Fluid pressure of urine.When coughing during storage stage, the back-pressure produced by valve Rise to match the quick and of short duration high-voltage pulse because of cough.When patient selection is urinated, prolonged relatively low pressure Applying causes the back-pressure for coming from valve slowly to reduce, final to disappear, and produces current.

In the present invention, prosthese is located at bladder inner side.Prosthese has valve, and it is located at the end of tubular conduit, A/C In position, and neck of urinary bladder and external sphincter are crossed.Tubular conduit can be soft or springy, or can be soft And with reinforcement region, it is used for anti-avalanche.Conduit portion can allow to urinate through its center flowing.

Tubular conduit can also have contoured region or positioned at along the region of its outer surface, to contribute to retaining it In urethra.The contoured region can be the form of bulbous construction, and so design is with male sex's anatomy In membranous urethra, proximal travel is prevented.Optionally, can prevent by bell mouth shape structure offer curves, to meet female urethra Only proximal travel.

The valve also bell mouth shape region with circumference, the region is contoured, to be close to the bladder wall.The region provides Sealing means, so that the outside that urine will not surround valve is flowed, and are directly through valve.In addition, the bell mouth shape region can be with With Nitinol line or polymer fiber reinforcement, to improve the resistance to distal migration.And, bell mouth shape region can be gas Ball.

In the original location, when the valves are closed, prosthese prevents urine from flowing.When the urine long-time in bladder exceedes predetermined fluid Pressure（A typical range of from 690-900mmH₂O continues 10sec）When, valve is opened.Because long-time is necessary condition, when being exposed to During compared with the pressure of short duration, valve will not be opened, or even significantly higher pressure will not open valve.For example, sneeze or Cough can apply enough pressure around lateral vesical, to produce 1200-1600mmH in bladder₂The Fluid pressure of O, But because it only keeps the 0.5-1 seconds, or or even iterative cycles, valve will remain turned-off.

Conduit, if softness, will not by any way expand urethra.However, it is the phase to make conduit with elastomeric material Hope, so that urethra is all stayed open at internal sphincter and external sphincter.This places one's entire reliance upon bladder so as to mean self-control Interior valve.In the case where the conduit in inner and outer sphincteral region is flexibility, so as to normally dissect power urethra is not result in Close, valve is placed in conduit, open under the Fluid pressure of the valve in similar to bladder.

With reference to Figure 68-70, another valve gear 800 according to the present invention is illustrated.Valve 800 includes hollow stem 801 and tool There is the head 802 of slit 803, flap is formed in slit.When slit 803 responds the pressure of applying and opens, urine is passed through The stream of head 802 enters in runner 804, and runner 804 extends through bar 801.Bar 801 also has bulbous portion 805, fixed to contribute to Position and original position of the holding meanss in neck of urinary bladder 806.

Figure 71-73 illustrates the delivering and expansion of the valve gear 810 with head 811, and the head 811 has valve 812 With bar part 813.Delivery system includes conduit 820, and it is entered in neck of urinary bladder.Valve gear 810 is maintained at Collapsible structure In conduit 820（Figure 71）.Device 810 launches from the distal end 821 of conduit（Figure 72）.During launching, valve gear 810 expands to open up Opening structure, conduit 820 is withdrawn with the near-end of expanding unit（Figure 73）.
